Specification of Letters iat'ent.

To all whom, it may concern:

Be it known that I, ANTHONY J W1z ,a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Seaming- Machines, of which the following is a specification, reference being had to the accompanying drawings,- forming a part thereof.

The main object of this invention is to facilitate closing and folding dewii double lo'ck seams against the bottoms or ends of sheet-metal vessels.

It consists in certain novel features of construction'and in the peculiar arrangement and combinations. of parts, as hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like characters designate the same parts in the several figures.

cured in the bed ei'i eihe e eieiiei with the thereon. The clamp is pressed and held downward against the form by means of a foot-lever u, connected by a rod 1), passing through the post 8, with a plate at its upper end bearing upon the hub of the arm 1, as shown in Figs. 1, 2 and 4. The foot-lever is locked in its lower position and theclamp g is held down against the tension of the spring t by means of a pivoted dog or detent w, as shown in Fig. 2. The post 8 may be set up or down in the bed 6 to adjust the clamp g and its supporting-arm 1" for use with forms a of different dimensions. To hold the bodysection of a vessel in place on the form, hand clamps or cams 90 w, as shown in Fig. 1, may be provided.

The slide or carriage f is provided at its in ner end with an upwardly-projecting crankpin and rollery, which engages with the groove 7c of the cam b, as seen in Figs. 1 and 2.

The bracket or standard j is adjustably secured upon said slide by a bolt 2, the head of which is engaged with a longitudinal undercut groove 2, formed in said slide or carriage, as shown in Figs. 1 and 3. The squared shank of the stem 'L, carrying the rotary. head h, is fitted and movable up and down in a vertical slot or opening in the upper end of said bracket or standard and is adjusted therein by means of a vertical screw 3, provided with a hand wheel or crank 4 at its upper end.

The head 7i is provided on its sides with three sets of seaming-rollers mounted on circular disks or blocks 5, which are fitted to turn in corresponding recesses in said head and are held therein, as shown in Figs. 7 and 9, by screws 6, threaded in said head and engaging at their ends w1th(grooves in the cylindrical shanks of said isks. On one of these disks are mounted the seaming-rollers 7 and 8 for the first operation. These rollers have plain cylindrical peripheries or faces and are set with their axes parallel with each other and perpendicular to the stem i. The roller 7, which is of greater diameter and has a wider face than the roller 8, is pivoted centrally on the disk 5, and on each side thereof in a line at right angles to a line passing through the centers of the rollers 7 and 8 a guiding-roller 9 is mounted on said disk, as shown in Fig. 8. The rollers 10 and 11 for the second operation are mounted in a similar manner on another disk or block 5 in another face of the head 7L and have opposing conical or beveled peripheries or faces. The smaller roller 11 is pivoted, as shown in Figs. 9 and 10, to a slide 12, fitted in a radial recess in the disk 5 and hearing at its inner end against a spring 13, which tends to thrust it outward. This slide bears at its outer end against and is held in place in the disk by the wall of the recess of the head h, in which said disk is fitted. Through the end of the head an opening is made with which the recess in smear;

said disk registers in one position, as shown in Fig. 9, and through which said slide may be thrust outward by the spring 13. This opening is normally closed by a keeper 14, hinged to the outer end of the head h and held in place by a thumb-screw 15. Between the roller 11 and the slide 12 is interposed a ring 16, which determines the space or distance between the opposing beveled faces of said roller and of the roller 10. A guiding-roller 9 is mounted on the same disk, with the rollers 10 and 11 on each side of the central roller 10, as shown in Fig. 10. The rollers 17 and 18 for the last operation are mounted on still another disk or block 5 in another face of the head h. The smaller roller 18 is in this case let into a recess in said disk and its axis is at right angles to the centrally-arranged roller 17 and radial with respect to the aXis of the disk 5, as shown in Figs. 11 and 12. The guiding-rollers 9, as in the other cases, are mounted on the same disk on both sides of the central seamingroller 17, as shown in Fig. 12.

The several sets of seaming and .guiding rollers may be arranged in any convenient or desired order on the lateral faces of the rotary head it, and each set is held in place when turned into working position with relation to the rotary form a by a spring-actuated locking pin or bolt 19, fitted in a radial socket in the head It and engaging at its inner end with sockets 20 in the periphery of a collar on the stem i.

The several seaming and guiding rollers are pivotally secured to the swivel disks or blocks 5 by means of shoulder-bolts, so that they can be unscrewed therefrom and replaced.

The machine hereinbefore described operates as follows: Bottom or end and body sections of a sheet-metal vessel having marginal flanges previously formed thereon being placed and clamped on the form a, as shown in Fig. 1, the first pair of seaming-rollers 7 and 8 is turned into and locked in working position, as shown in Figs. 1 and 7. The bracket or standard 7' is then adjusted on the slide or carriage f to bringthe space between said seaming-rollers directly above the marginal flanges of the vessel-sections on form a, as shown in Fig. l. The head h is then moved down, by means of the screw 3, till the rollers 7 and 8 assume the positions in which they are shown in Fi 7 with relation to the work, the inturned ange on the body-section of the vessel bending or yielding as the seaming-rollers are brought into working position. The form a, is now set in motion through its driving connections, and as it turns the rollers 7 and 8 close the inturned flange on the body-section against the flange on the bottom or end section, as shown in Fig. 7, the disk 5 turning in the head it and assuming different positions therein, according to the position of the rotary forma and the direction of the seam, as indicated in Fig. 8. The slide f with the head h are moved back and forth by the cam b as the form (1, turns, so as to keep the seaming-rollers in their proper operating relation to the work whatever the shape of the form may be. After the completion of the first operation the head h is raised and turned to'bring the next set of rollers into operative position. The form a being stopped, the head it is lowered to bring the rollers 10 and 11 into working position with relation thereto, as shown in Fig. folded seam as left by the first set of rollers being turned inward between the opposing beveled faces of the rollers 10 and 11. The form a is now set in motion again, and as 'it turns the folded flanges of the vessel are turned inward toward the axis of the vessel, as shown in Fig. 9. When this operation is completed, the form is stopped, and the keeper 14 may be unfastened by removing the screw mit the roller 11 to be moved by the spring 13 away from the roller 10. The head h can now be raised to carry the seaming-rollers away from the work. Usually the metal will spring or yield enough to permit the withdrawal of the rollers 10 and 11 from the inturned seam without separating them, so that it is not always necessary to unfasten the keeper 14 and release the slide 12 and roller 11. The next and last pair of rollers 17 and 18 is now turned and moved down with the head It into working position, as shown in Fig. 11. The form a is started, and as it turns past said rollers the seam is pressed from the position in which it is left by the rollers 10 and 11 down against the bottom or end of the vessel, asshown in Figs. 11 and 14. The seam being completed by this last operation, the nut or bolt 2 is loosened, the bracket j,wi-th the head it, is drawn back to clear the vessel on the work-supporting form, the clamp q is released and swung to one side out of the way, the clamps'ac are disengaged from the rim of the vessel, and the vessel is then removed from the form and replaced by flanged sections to be joined together by repeating the series of operation, as above explained.

Various changes in the details of construction and in the arrangement of parts of the machine may be made without materially affecting its principle and mode of operation and without departing from the spirit and intended scope of the invention.
